IMPROVEMENT IN VAPOR-BURNERS..

Specification forming part of Letters Patent No. 115,089, dated May 23,1871.

I, ALANsoN F. NOBLE, of Indianapolis, in the county of Marion and Stateof Indiana, have invented certain Improvements in Vapor Lamp-Burners, ofwhich the following is a specification Natm'e and Objects of thcInvention.

My invention relates to improvements in that class of lamp-burners inwhich hydrocarbon liuids are employed and vaporized to produce gas; andit consists in acertain construction and arrangement of the severalparts of which the burner is composed, by which it is rendered moreconvenient to use and more et'- ticient in operation than thoseheretofore in use, as will hereinafter more fully appear.

Description of the Accompanying Drawing.

Figure 1 is a side elevation of a burner embodying my invention. Fig. 2is a vertical section through the center ot' the same. Fig. 3 is ahorizontal sect-ion through the heater and auxiliary burner, by whichthe iluid is vaporized.

General Description.

A A A is the stock or principal part of the burner, and to which all theother parts are attached. A is the stem connecting the burner with thefountain or elevated reservoir; A is the body or' the burner, containingthe vaporizing-chamber I; and A is the top or upper part of the stock,on which are arranged the mixing-chamber B having the burner H in thetop, and the heating-chamber G with the auxiliary burner E, as shown,the parts B,

H, and C E being similar to burners already in use. My first improvementconsists in the construction of the stock A A A, which is clearly shownin the section drawing, Fig. 2. The end of the stem A, connecting withthe tube leading from the elevated reservoir in which the lluid isplaced, is chambered, as shown, for about half its length, to receivefibrous packing, and the remainder ofthe stein connecting with the bodyA is drilled through, forming a small tube to connect thispackingchamber with the vaporiZing-chamber I.

One object ot' this construct-ion of the stemA is to provide aconvenient means of renewing the packing when required, as the burnermay be readily unscrewed by hand from the tube connectiu g with thereservoir. Generally the stein will be screwed into a stop-cock placedat the end ot' the tube leading from the reservoir, so that by means ofthe stop-cock the ilow ot' the fluid into the packing-chamber may befully controlled either with or without the packing.

The advantage of this construction ot' the stem will be betterappreciated when it is understood that, on account ofthe varyingqualityot the uid employed, the packing may become in such condition as toentirely obstruct the ilow through it into the vaporizing-chamber I, inwhich case the burner may be readily unscrewed and the packing eitherrenewed or entirely removed, as may be found most convenient ordesirable, this construction ot' the stem being also designed to obviatethe necessity of packing. Another object in constructing the stem inthis manner is to avoid placing the packing in too close proximity tothe heated vaporizing-ehamber, as the great heat required to vaporizethe duid is liable to char and render the packin g untit for the purposedesigned, which is to control and regulate the flow of the iuid into thevaporiZing-chamber I.

c is a removable plug screwed into the upper part A of the stock, havinga small tapering hole in its center, through which the vapor issues fromchamber I/into the mixing-chamber B, where it is mixed with air. Thisremovable plug provides a ready and cheap means ot' repairing the burnerin case the orifice therein becomes enlarged, s3 that the end ot' thevalve-rod Gr does not lill it perfectly. All ot' the upper portion oftheburner-consisting of the mixing-chamber B, heating-chamber C, auxiliaryburner E, and vaporizing-chamber* is similar to burners already in use,except that the heating-chamber C is formed as shown in Fig. 3, so thatthe llame that issues from the small hole near the bot-.tom of theauxiliary burner E will impinge upon the inward-curved surface of theheating-chamber and be delected back against the upper part A of thestock containing the vaporizing-chamber I, by which the latter will bemore effectively heated, and thereby more rapidly vaporize the fluidcontained in it. rlhe heating-chamber is attached to the upper part Alot' the stock by means of a collar, D, that encircles it, thus renderingthe slit in the burner H susceptible ot' being turned, so as t) presentthe broad side of the flame in any desired direction without thenecessity of moving the lamp.

In connection with the several parts of the burner constructed andarranged as above described I emplo5v the Well-known regulatingandcut-ofi' valve-rod G, which I have arranged to stand in a verticalposition under the mixingchamber B, so that the jet of vapor will ascenddirectly toward the center of the burner H and not mpinge upon the sidesof the chamber, as is the case with some burners, whereby the ame isrendered clearer and more brilliant, and the tendency to smoke isavoided.
